NEWS file for the gridGeometry package

Changes in version 0.4-0

• New functions grid.polyoffset() and grid.polylineoffset() for generating offset regions.

• New function grid.minkowski() for generating Minkowski sums of grobs.

Changes in version 0.3-1

• The default op for xyListFromGrob() is now "flatten" when closed = FALSE.

• The default closed value for xyListFromGrob() (at least) is now determined by isClosedShape().

• New grid.reduce() function.

Changes in version 0.3-0

• Add dependency on R 4.2.0 because works with more complex classes returned by grobCoords.

• New xyListFromGrob() function to reduce grob (or gTree) that contains potentially multiple shapes to a single list of sets of x/y coordinates (for input to polyclip routines).

• Makes aliases for xyListPath() etc named xyListToPath() etc (to match new xyListFromGrob() function).

Changes in version 0.2-0

• Add dependency on polyclip 1.10-0 because that now supports clipping of "open" polygons (lines). No more need for polyclip fork.

Changes in version 0.1-0

• Add dependency on R 3.6.0 because require new grobCoords function.
